An ultra-thick and creamy keto peanut butter milkshake with almond milk, no store-bought sugar-free ice cream needed! An easy 6-ingredient homemade keto milkshake recipe to fix your summer sweet craving with only 3.6 grams of net carbs.

What’s a keto milkshake?

A keto milkshake is a sugar-free frothy cold drink usually made of ice cubes, almond milk, and cream.  It doesn’t require store-bought keto ice cream and can be made at 100% at home with the most simple ingredients. It is a delicious keto snack to refresh in summer or breakfast on the go.

How to make a keto peanut butter milkshake?

Yes, you can have peanut butter on a keto diet as long as you are using unsweetened peanut butter with no added vegetable oils.

However, even if natural peanut butter is keto-friendly, it still contains a decent amount of carbs, so you have to use it sparingly.

That is why this keto milkshake uses only 1 1/2 tablespoon of peanut butter. It brings out all the peanut butter flavor you are craving without adding too many carbs to your low-carb milkshake.

  • Peanut butter – you can use any nut butter you like. Almond butter is a great option too to decrease carbs. I made this low-carb milkshake many times. Other options that I love are cashew butter, coconut butter, or almond butter.
  • Unsweetened almond milk – or unsweetened vanilla almond milk for a hint of vanilla flavor.
  • Unsweetened cocoa powder
  • Chia seed – I won’t skip them even if they add 1 g net carb per serve. They thicken the milkshake and add proteins!
  • Heavy cream or use full-fat dairy-free coconut yogurt. Other options are full-fat Greek Yogurt or canned coconut cream.
  • Sugar-free crystal sweetener – I love to use Monk fruit crystal sweetener, but you can also replace this with few drops of liquid stevia. Read my full review of Keto-friendly Sweeteners to learn some more!
  • Ice cubes – that is what makes the drink frothy like a milkshake without using sugar-free ice cream.

Keto milkshake with almond milk

This is a keto milkshake recipe using almond milk. In fact, unsweetened almond milk is the best option to create low-carb smoothies or milkshakes as it is very low in carbs.

When should I drink keto milkshake?

Honestly, I am having this keto chocolate peanut butter milkshake any time of the day. I love it for breakfast after a run to reload my body with protein and enjoy a fresh drink. It’s also a delicious treat in the afternoon during summer or a great dessert alternative when you crave something sweet quickly.

  • In a blender, add all the ingredients and blend until smooth and frosty. I always start with 3/4 cup ice cubes, blend and adjust depending on how frosty I want my milkshake.
  • Taste and adjust sweetness with an extra tablespoon of erythritol or stevia drops. Blend for a few seconds to combine and serve.
  • Serve immediately in 2 small milkshakes (or 1 large) with a drizzle of melted sugar-free chocolate, a drizzle of peanut butter, a dollop of dairy-free yogurt or unsweetened whipped cream, and chopped peanuts.


  • You can store the leftover in the fridge for up to 24 hours. The next day I won't be as frothy, bring back to the blender with few ice cubes, and serve immediately!
  • Freeze the leftover in a popsicle mold! It makes a delicious keto singe serve ice cream to snack on.
Nutrition panel is for 2 small milkshakes without the optional chia seeds. Seeds add nutrients but still 1g net carbs per serve.

    Wow! Now this is what I call heaven in a glass.
    I needed something sweet, so I thought that I would give this recipe a go. I’m so glad that I did. I have never tried a peanut butter milkshake before. The taste is phenomenal. I will definitely be having this again very soon.
    Well done Carine! You are doing an amazing job. Keep up the good work.

    Perfect!! It tastes just like the smoothie I used to get at smoothie king, but without all the carbs! I also added ground flaxseed instead of chia.

    I rarely review recipes because most of them come out just ‘okay’. This recipe is AMAZING! I usually make diabetic and keto desserts and end up eating them just because I made them without actually enjoying them. I loved this one so much. thanks for sharing! Game changer!

    • Thanks for this amazing comment! I am so happy you found my blog then, I have so many delicious diabetic friendly desserts for you to try here! Enjoy, XOXO Carine

    My daughter and I just found your recipe…saved our lives as we were craving a shake but trying to reduce carbs with our diet. It was delicious! Used the Eryth/Monk fruit sweetener and we like it so much better than Stevia. Thanks so much!

    • I am sorry to hear that the sweetness wasn’t to your palate. We all have different sweet tooth and that is why the recipe states that you have to adjust sweetness with as much stevia drops as you like. The recipe suggest a minimum sweetness that is easily adjusted with few extra drops of liquid stevia or pinch of erythritol. It has nothing to do with the cocoa powder. If you decrease cocoa powder your milkshake won’t have cocoa flavor at all. Also, you shouldn’t add ice cream as this will change the texture and if not sugar free it will adds up carbs and sugar. I hope you try the recipe again following those tips and enjoy your keto drink! XOXO Carine.

    I substituted almond butter for peanut butter, heavy cream for yogurt, and used swerve as my sweetener and this came out perfect! Thank you! I really needed something sweet!

    • My pleasure ! We all deserve something sweet on keto right? Enjoy the keto baking recipes on the blog. XOXO Carine.
